The popular Facebook group “Aikido” shares well-written content about the traditional martial art, and the technical notebook.
Aikido makes use of body movement (tai sabaki) to blend with uke. For example, an “entering” (irimi) technique consists of movements inward towards uke, while a “turning” (転換, tenkan) technique uses a pivoting motion. Additionally, an “inside” (内, uchi) technique takes place in front of uke, whereas an “outside” (外, soto) technique takes place to his side; a “front” (表, omote) technique is applied with motion to the front of uke, and a “rear” (裏, ura) version is applied with motion towards the rear of uke, usually by incorporating a turning or pivoting motion. Finally, most techniques can be performed while in a seated posture (seiza). Techniques where both uke and tori are sitting are called suwari-waza, and techniques performed with uke standing and tori sitting are called hanmi handachi.
